The rain stopped, and tide went out, and we walked across the causeway to Callot.
There is something liminal and tantalising about islands accessible at low tide, with their causeways which appear and disappear. Short of staying here, at least for the twelve hours between tides, or perhaps using a small boat, you can't really have a sense of this as an island, but more as a straggle of sandy outcrop, rock and mussel beds extending from the peninsular of Carentec.
The chapel, it's said, has been a place of pilgrimage for more than a thousand years, the corsaires sailing out of Morlaix to do battle with the English would salute it as they passed with a cannonshot,
and clearly it's much frequented and gifted with votives and artworks still; one of the plaques on the wall above was for a fisherman lost at sea in 2004.
I couldn't find out anything about the painting above however, one of a pair.
A lovely walk, and another corner of the bay to explore.
